“…In accessing services in other domains such as Kerberos, users' identities usually could not be recognized or it involves extremely complex operations for cross-domain authentication. By leveraging the distributed consensus of the blockchain, Chen et al [61] propose an efficient cross-domain authentication scheme named XAuth. In their work, to improve the response speed arising from the low throughput of blockchains as well as protect user privacy, the authors design an optimized blockchain approach and privacy preservation functions in cross-domain authentication.…”

Metaverse, as an evolving paradigm of the nextgeneration Internet, aims to build a fully immersive, hyper spatiotemporal, and self-sustaining virtual shared space for humans to play, work, and socialize. Driven by recent advances in emerging technologies such as extended reality, artificial intelligence, and blockchain, metaverse is stepping from science fiction to an upcoming reality. However, severe privacy invasions and security breaches (inherited from underlying technologies or emerged in the new digital ecology) of metaverse can impede its wide deployment. At the same time, a series of fundamental challenges (e.g., scalability and interoperability) can arise in metaverse security provisioning owing to the intrinsic characteristics of metaverse, such as immersive realism, hyper spatiotemporality, sustainability, and heterogeneity. In this paper, we present a comprehensive survey of the fundamentals, security, and privacy of metaverse. Specifically, we first investigate a novel distributed metaverse architecture and its key characteristics with ternary-world interactions. Then, we discuss the security and privacy threats, present the critical challenges of metaverse systems, and review the state-of-the-art countermeasures. Finally, we draw open research directions for building future metaverse systems.

“…4) Cross-Chain Identity Authentication: By getting rid of trusted third parties, blockchain technology is fundamental to build trust-free digital identities for users in various domains in the metaverse [73], [74]. As distinct sub-metaverses may deploy services on heterogeneous blockchains to meet quality-ofservice (QoS) requirements, efficient cross-chain authentication is needed for seamless services across multiple sub-metaverses.…”

“…Kubilay et al (2019) proposes CertLedger, a blockchain-based architecture with certificate transparency and eliminates the traditional insufficient and incompatible certificate validation processes implemented by different software vendors. Chen et al (2021) proposes a cross-domain authentication solution XAuth that separates the storage and control layers and designs an efficient cross-domain data management mechanism and cross-domain anonymous authentication protocol. proposed a multi-Certificate Authority (CA)-based authentication architecture to establish distributed trust among multiple domains and share cross-domain certificate information.…”

This paper proposes a hierarchical framework for industrial Internet device authentication and trusted access as well as a mechanism for industrial security state perception, and designs a cross-domain authentication scheme for devices on this basis. The scheme obtains hardware device platform configuration register (PCR) values and platform integrity measure through periodic perception, completes device identity identification and integrity measure verification when device accessing and data transmission requesting, ensures secure and trustworthy access and interoperation of devices, and designs a cross-domain authentication model for trustworthy access of devices and related security protocols. Through the security analysis, this scheme has good anti-attack abilities, and it can effectively protect against common replay attacks, impersonation attacks, and man-in-the-middle attacks.
